Analysis technique for flexural behavior in RC beam considering autogenous shrinkage effect
چکیده انگلیسی
This study intends to evaluate an effect of AGS (Autogenous Shrinkage) on flexural behavior in RC member. For this work, AGS tests are performed considering mineral admixtures like fly ash and slag. Based on the test results, previous prediction technique for AGS is modified. The modified technique is considered in the previously developed FE program. Through the FE program with AGS effect, the flexural behaviors in RC beams are evaluated and analyzed. The tensile stresses and deflections in the middle span of RC beam increase by 20-27% and 5.2-10.8%, respectively due to the effect of drying shrinkage and AGS. The reasonable technique is proposed through considering the models for material and structural behavior.
